Has anyone any experience of the Hoya Pro1 Digital Filters & are they worth spending almost twice as much over normal coated filters.

Is the coating robost enough to enable 'washing' when the front becomes contaminated with salt spray, dust etc.

Here's the comparison - decide for yourself if it's worth it

Nice of you to post this samples but I'm still wandering how do they compare to a "no filter" shot.

Agreed. I'm interested in the same thing.
Filters will always degrade image quality no matter how good they are.

Using a lens without a filter is something that I don't do so my comparison was based on whether the Hoya Pro1 achieved any noticable improvement over the non coated filter - I think it does BUT is it worth paying 3 times as much as flare is still apparent, abeit reduced.

You might like to visit this site with the following Finnish translation:

For how much different coatings matter here's good page:

And no, it isn't encrypted, it's just in Finnish.

First shot is with good multicoated lens, in second there's uncoated El Cheapo in front of it, in third pic there's one layer coated El cheapo (with really bad optical quality, double reflection). Fourth pic is with high quality multilayer coated filter.

Next photo is ND filter with single coating layer in one side, after that there's uncoated CPl (but high quality one because reflection is symmetrical)
Last real condition shots have same "configuration" as in first four.
